Description

A building waste crushing device

technical field

The utility model relates to a crushing device, in particular to a crushing device for building waste.

Background technique

With the development of the economy, the advancement of urbanization, the reform of the countryside, and the construction of new houses in the countryside have occurred in various places, and the generated building waste has become a major factor affecting the appearance of rural villages. The building waste is piled up randomly without treatment, which seriously affects the rural environment; if it is randomly filled, the waste is not dense, and problems such as ground subsidence at the landfill will occur in the later stage. Due to the large size of waste, it is not convenient to recycle and reuse, and it is randomly piled or landfilled, which not only causes damage to the environment, but also leads to a waste of resources.

There are many types of crushers in industry, and they are widely used in mining, cement manufacturing and other fields. However, because the above-mentioned crushers are relatively large in size and inconvenient to move, it is unrealistic or costly to use the above-mentioned crushers for rural and urban self-employed.

At present, there are few small crushers on the market, and most of them are large single-stage crushing devices. Due to various reasons, the crusher's crushing operation of building waste is limited.

Contents of the invention

Aiming at the existing technical problems, the utility model provides a simple, economical, and movable small-batch building waste crushing device, which can crush small-batch building waste such as clay bricks, stones, and cement blocks in rural areas and towns. etc. for crushing and refining, so that building waste can be piled up, landfilled, or recycled as aggregate.

The technical solution adopted by the utility model to solve the technical problem is: a building waste crushing device, which includes a chassis, a bracket, a primary pressure roller and a secondary pressure roller; four walking rollers are installed on the underside of the chassis. One end is designed with a bracket for dragging and removing; the bracket is fixed on the chassis, and one side of the bracket is designed to provide three pairs of pressure rollers (one pair of primary pressure rollers and two pairs of secondary pressure rollers). The driving motor of power; the first-stage pressure roller is placed on the support, and the upper side is designed with a waste material inlet, and a stripping block is designed around it to prevent the material from adhering to the first-stage pressure roller and affecting the crushing effect; There are two pairs of secondary pressure rollers mentioned above, which are also placed on the bracket, symmetrically distributed on both sides of the vertical center line of the primary pressure roller, and there are also stripping blocks around the secondary pressure roller, and a crushed material discharge is designed on the lower side The first pressure roller and the second pressure roller are surrounded by the inner protective plate and the outer protective plate, which play the role of sealing protection. The top of the inner protective plate is raised, which is conducive to the diversion and dispersion of materials; Each pair of pressure rollers of the stage pressure roller rotates in the opposite direction, the spacing can be adjusted, and the number of convex lines on the surface of each pair of pressure rollers is different; in the above device, the building waste is fed from the feed port, and the pressure rollers are driven by the motor (the primary pressure roller and the secondary pressure roller) move to crush and refine the building waste, and the material is discharged through the discharge port to complete the crushing operation.

The beneficial effects of the utility model are: the utility model is a movable crushing device with high flexibility, and it is more economical and practical to crush small batches of building waste in rural areas and towns; the device is secondary crushing, crushing and refining The effect is good, without repeated crushing, which reduces the labor workload; the number of protrusions of each pair of pressing rollers of the device is different, which is conducive to crushing and refining; the crushing and refining of building waste increases the density of material stacking, reduces the In order to occupy space, for waste landfill, the gaps between particles are small, and there will be no ground subsidence in the later stage; the crushed and refined materials can be used as roadbed fillers or mixed with cement in the form of aggregates as building materials, and the waste Turning waste into treasure, recycling, saves resources, protects the environment, and is also conducive to improving the environment in rural and urban areas.

Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings and examples, wherein the schematic implementation and description are only used to explain the utility model, but not as a limitation to the utility model.

As shown in Fig. 1, Fig. 2, Fig. 3, and Fig. 4, a kind of building waste crushing device, this device comprises chassis 1, support 5, primary pressure roller 10 and secondary pressure roller 11; Described chassis 1 Four walking wheels are installed on the lower side, and one end is designed with a bracket 2 for dragging and removing; the bracket 5 is fixed on the chassis 1, and one side of the bracket 5 is designed with three pairs of pressure rollers (the first-level pressure roller 10 a pair and two pairs of secondary pressure rollers 11) drive motor 6 that provides power; the primary pressure roller 10 is placed on the support 5, the upper side is designed with a waste material inlet 4, and a stripping block is designed around it 9. Prevent the material from adhering to the primary pressure roller 10 and affect the crushing effect; there are two pairs of secondary pressure rollers 11, which are also placed on the bracket 5, symmetrically distributed on both sides of the vertical centerline of the primary pressure roller 10. On the side, the secondary pressure roller 11 is also designed with a stripping block 9, and the lower side is designed with a crushed material discharge port 3; the primary pressure roller 10 and the secondary pressure roller 11 are surrounded by the inner protective plate 8 and the outer protective plate 7, Play the role of sealing protection, the top of the inner protective plate 8 protrudes, which is conducive to the diversion and dispersion of materials; the rotation direction of each pair of pressure rollers of the primary pressure roller 10 and the secondary pressure roller 11 is opposite, and the distance can be adjusted, and each The number of convex lines 12 on the surface of the pressure roller is different; in the above device, the building waste is fed from the feed port 4, and the pressure rollers (primary pressure roller 10 and secondary pressure roller 11) are driven to move under the action of the motor 6, The building waste is crushed and refined, and the material is discharged through the discharge port 3 to complete the crushing operation.

When the utility model is in use, start the motor 6 to make the crushing device work first, then use a dump truck, a forklift or other tools to put the building waste into the feed port 4, and the waste is in the first-stage pressure roller 10 and its convex strip 12 Under the action, it gradually enters between the first-stage pressure rollers 10, and the building waste is subjected to primary crushing. The materials adhering to the first-stage pressure rollers 10 are separated from the first-stage pressure rollers 10 under the action of the stripping block 9, The crushed material is automatically scattered, and under the diversion and dispersion effect of the protrusion of the inner protective plate 8, it enters between the secondary pressure rollers 11, and is crushed again under the action of the secondary pressure roller 11 and its convex strips 12, sticking The material attached to the secondary pressure roller 11 is separated from the secondary pressure roller 11 under the action of the stripping block 9, and the broken material flows out from the discharge port 3 under the guidance of the inclined plate at the bottom of the inner protective plate 8 ; The outer protective plate 7 mainly prevents material from flowing out and splashing out, and hurting others. After the crushing operation is completed, the bracket 2 is connected to the tractor, and then it can be moved to other places for crushing operation, which has greater flexibility.
